Some people find it easier to add or subtract whole numbers but yes, you could round to the nearest half.
When rounding to the nearest whatever, half the number round up and half round down. → the numbers that round to 170000 to the nearest 10000 are 170000 ± (10000 ÷ 2) = 170000 ± 5000 However, if a number is exactly half way, the convention is to round them up, so the numbers in the range: 170000 - 5000 ≤ number < 170000 + 5000 → 165000 ≤ number < 175000 will round to 170000 to the nearest 10000 → smallest number is 165000 → biggest [whole] number is 175000 - 1 = 174999
